Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive at least one signal from a second wireless device, the at least one signal including one or more of RTP information or inertial sensor information. The apparatus may determine at least one AoA measurement and at least one RTP measurement associated with the at least one signal received from the second wireless device. The apparatus may determine a path of trajectory of the second wireless device based at least in part on the at least one AoA measurement, the at least one RTP measurement, and the inertial sensor information.

Abstract: Certain aspects of the present disclosure generally relate to magnetometer calibration. In some aspects, a device may obtain multiple sets of magnetic field measurements corresponding to multiple local magnetic field strengths, wherein each set of magnetic field measurements is measured in association with an unknown local magnetic field strength. The device may calculate multiple error values using the multiple sets of magnetic field measurements, estimated values of the multiple local magnetic field strengths, and estimated hard iron bias values. The device may identify a set of hard iron bias values for magnetometer calibration based at least in part on comparing the multiple error values. The device may calibrate a magnetometer using the identified set of hard iron bias values.

Abstract: Various embodiments provide systems and methods which disclose a device which may be used to determine an audio event based on receiving an audio signal. Based on the determined audio event, audio activity may be tracked. The tracked audio activity may be summarized based on a summary mode. Feedback of the summarized tracked audio activity may be based on a feedback mode.

Abstract: Disclosed are systems, devices and methods for determining a range between devices based, at least in part, on measurements of wireless tone signals transmitted between devices. In particular, two devices may measure tone signals transmitted between the two devices for determination of a round-trip phase measurement. Obtaining multiple round-trip measurements from tone signals transmitted at different carrier frequencies may enable resolving at least some range ambiguities.
